The Telecom Defense Limited Company has one mission: keeping mobile networks worldwide safe from threats against privacy of subscribers, fraud and denial of service attacks that have emerged recently over signaling networks such as SS7 and Diameter.

Our unique off-premises SS7 and Diameter penetration tests and security audits can tell you quickly if your network is vulnerable. And we can provide training to your staff on how to remediate these vulnerabilities as well as assist with the implementation of signaling firewalls.
